Indipendently taught chemistry and biology for two classes of about 15 students Create lesson plans personalized and redact profile for each student for the final examinations

The training period has been finalized learning procedures for accreditation to ISO 17025 and the preparation of control charts. In addition, the laboratory work has been aimed at the determination of food additives (nitrites,nitrates, sulphites) through the use of HPLC and other chromatographic techniques

I managed the customer and the counter sales and I edited the graphics and advertising of the store.
